WRAPPING-MACHINE.

Patented July 24L, 191W.

Application filed May 6, 1916. Serial No. 95,819.

I To all whom it may concern:

Be it known that I CARL BECKMANN, a citizen of the United tates, and aresident of the city ofNew York borough of Brooklyn, in the county ofKings and State of New York, have invented a new and ImprovedWrapping-Machine, of which the following is a full, clear, and exactdescription.

This invention relates to a machine construction for automaticcartoning'machines, bottle wrapping machines, package making machines,etc., and it has to deal more particularly with means for automaticallyfeeding the cartons,rbottles, packages or the like to and from thevarious mechanisms which go to make up the machine.

The invent1on has for its general objects to provide a novel mechanismwhereby the articles are fed successively through the machine in anexpeditious and effective manner, the invention being particularlyadapted for that type of machine which employs a plurality of rotary ortraveling carriers in which the filling, closing and sealing of thecartons takes place successively, the mechanism having simultaneouslyacting parts whereby an empty carton is fed to one car rier, while afilled carton is transferred from one carrier to the other, and a filledand sealed carton discharged from the final carrier; and the same istrue whether the carriers are used for wrapping bottles or otherarticles'or the makin of packages.

A more specific ob ect of the invention is the provision of a mechanismembodying simultaneously acting feeding, transferring and deliveringmeans mounted on a common element which is supported by parallel linksand receives reciprocatory motion by movement of the links, whereby thefeeding to one part of a carrier, transferring from another part of suchcarrier to a second carrier, and delivering from such second carrier,can take place at one and the same time. With such objects in view, andothers which will appear as the description proceeds, the inventioncomprises various novel features of construction and arrangement ofparts which will be set forth with particularity in the followingdescription and claims appended hereto.

In the accompanying drawings, which illustrate one embodiment of theinvention and wherein similar characters of reference indicatecorresponding parts in. all the views,

Figure 1 is a side view of the machine construction;

Fig. 2 is a plan view;

Fig. 3 is a sectional view on the line 33, Fig. 1;

Figs. 4 and 5 are detail views showing the folding of the flaps of thecarton incident to the transference of a carton from one carrier to theother; and

Figs. 6 to 9 inclusive are end views of the carton, showing thesuccessive steps in the folding of the flaps.

Referring to the drawing, A and B desig nate two rotary carriers whichare disposed parallel to each other to rotate on horizontal axes, andthese carriers are so designed as to enable the filling, closing andsealin of cartons, the filling taking place in the 11st carrier, partialclosing taking place while passing from the first to the second carrier,and the final closing and sealing while discharging from the secondcarrier, but it is to be understood that these carriers may be designedfor the wrapping or labeling of other articles, or for the making ofpackages.

The empty cartons are supplied from a hopper C by an upsetting machinedisclosed in a eo-pending application filed by me. The

cartons are supplied successively to a guideway D by a horizontalfeeding bar 1 which causes the cartons to more step by step through theguideway D to the first carrier A. The carriers rotate step by step intimed relation to the reciprocation of the feeding bar 1. The means forfillin the cartons and pasting the flaps are not disclosed, as they arewell known; The carton after being filled in the first carrier istransferred to the second carrier by transfer fingers 2 located betweenthe carriers, and finally the carton is discharged'from the secondcarrier by discharging fingers 3, which cause the sealed cartons to movestep by step. through a guideway E at the delivery end of the machine.The feeding means 1, transferring means 2 and the delivering means 3 arecarried by horizontal bars 4 at opposite sides of the machine. Thesebars are supported on the upper ends of vertical parallel links 5pivoted at 6 on the base 7 of the machine. By supporting the feeding,transferring and delivering means in this manner they all move to theright or left,'simultaneously, and consequently there will be asimultaneous feeding of a carton to the carrier A, the transfer of afilled carton from the carrier A to the carrier B, and the delivery ofthe sealed carton to the guideway E. In Fig. 2 an empty carton b isshown just in front of the feeding bar 1, while a filled but partiallyclosed carton b is shown just in front of the transfer fingers 2, and asealed carton b is shown in front of the delivery fingers 3. When thelinks 4 are moved to their limit toward the 'left, the bar 1 and fingers2 and 3 will be so positioned that an empty carton can be deliveredupwardly from the upsetting mechanism at c and a' filled carton can movedownwardly in front of the fingers 2 and a sealed carton move downwardlyin front of the fingers 3, it being understood that the carriers rotatein a clockwise direction. The bars 4 can be reciprocated in any suitablemanner, as, for instance, by an eccentric rod 8 connected at 9 with therear links 5, and receivin motion from an eccentric 10 which is drlvenby a transmission 11 from a motor 12.

The carriers in the present instance are shown as rotary drums havingpockets on the periphery so designed that the cartons will be held withtheir length parallel with the axis of rotation, so that the end flapsof the cartons will be in, the best position for closing and sealing.Each pocket embodies a pair of plates 15 forming the side walls of thepockets, the pockets being open at the ends, and in fact, the yieldingwalls 15 are in the form of jaws pivoted at 16 on the body of thecarrier, whereby the jaws constitute a mouth into which a carton orother article can be inserted, and after the inser tion the article willbe held by reason of the closing pressure exerted b the springs 17. Thecartons enter the poo rets radially and are pushed out radially, andbeing pushed out, only the frictional grip of the walls 15 need beovercome. When an empty carton is fed into the carrier A, all of the endflaps of the carton are open, as shown at the left as in Figs. 4' and 6.As the carton is being transferred by the transfer members 2, foldinglevers 20 engage the flaps f and fold the latter downwardly over theup-folded flaps f,

as shown in Figs. 5 and 7. The levers 20 are fulcrumed at'21 on the bars4, so that as the latter move to the right, the lower free ends 22 ofthe levers 20 will engage the stationary fingers 18 and thereby theupper ends of the levers 20 will have a downward as well as a lateralmovement to effect the folding down of the flaps f. During this time thetransfer fingers 2 move the carton from the carrier A into an aliningpocket of the carrier B. At the ends of the pockets of the carrier B arefolding fingers 23 which fold on back flaps f when the carton enter'sthe pocket of the carrier B, this step being shown in Fig- 8. After thecarton has been transferred to the carrier B it is progressively movedto a position in alinement with the discharge chute or guideway E, andwhen at this point the filled carton' is discharged by the fingers 3.Atsome point in the travel of the carton to the point of discharge,paste-applying means (not shown) applies paste to the flap f. This flapf is folded back by means of bars e at the sides of the dischargeguideway E, and these bars are of suflicient length as to hold the flapfirmly while the paste sets and during the step-by-step movement of thefilled cartons in the guideway E.

From the foregoing description taken in connection with the accompanyingdrawings, 9 the advantages of the construction and method of operationwill be readily understood by those skilled in the art to which theinvention appertains, and while I have described the principle ofoperation, together with the machine which I now consider to be the bestembodiment thereof, I desire to have it understood that the machineshown is merely illustrative and that such changes may be made whendesired as fall within the scope of the appended claims.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:
